- This invention relates to heel savers for shoes.

An object of this invention is to provide a heel for a mans or womans'shoehaving means to prevent the heel from wearing away too quickly andto insure degree of uniformity of wearing.

A further object of this invention is to provide a heel for a shoehaving a screw threaded longitudinal opening with coarse threads and acollar screwed therein and having an axial screw threaded openingreceiving a screw to contact the ground, the inner screw beingadjustable as it wears to compensate for wearing, the screws beingreplaceable when worn away.

A still further object of this invention is to provide in a heel of thecharacter described, coarse left hand threads on the outside of thecollar, and standard right hand threads for the inner screw, so that asthe inner screw is unscrewed, the outer collar will not be unscrewedtherewith.

Still another object of this invention is to provide a strong, compactand durable heel construction of the character described, which shall berelatively inexpensive to manufacture, easy to adjust, and yet practicaland eflilcient to a high degree in use.

Other objects of this invention will in part be obvious and in parthereinafter pointed out.

The invention accordingly consists in the features of construction,combinations of elements, and arrangement of parts which will beexemplified in the construction hereinafter described, and of which thescope of application will be indicated in the following claims.

In the accompanying drawing, in which is shown various possibleillustrative embodiments of this invention,

Fig. i is a side elevational view of a portion of a mans shoe providedwith a heel, embodying the invention;

Fig. 2 is a bottom plan view of the heel shown in Fig. 1;

Fig. 3 is a perspective view of the key for unscrewing the collar shownin Fig. 1;

Fig. 4 is a perspective view of a key used to unscrew the inner screw;

Fig. 5 is a perspective view of an inner screw with a hexagonal wrenchopening;

Fig. 6 is a perspective view of a wrench for unscrewing the screw shownin Fig. 5,

Fig. 7 is a side elevational view of a ladys shoe with a heel, embodyingthe invention; and

Fig. 8 is a bottom plan view oi the heel shown in Fig. 7.

Referring now in detail to the drawing, I0 designates a shoe here shownas a mans shoe, provided with a heel ll embodying the invention. Theheel l i may be made of leather or any other suitable material and isformed with a plurality of'vertical, spaced, screw threaded openings I2.5 The threads of the screw threaded openings 12 may be coarse and arepreferably left handed threads.

7 Screwed within each opening I2 is a collar or tube l4, having outerthreads l5 receiving the 10 threads of the openings l2. The tubes M areof such length as to stop short of the bottom surface l6 of the heel ll,so as not to contact the ground. Said tubes are each formed with aninternally screw threaded axial opening l1, pref- 15 erably havingstandard screw threads to receive a screw I8 of uniform diameter. Thelower end of the screw I8 is flush with the under-surface of the heelII.

The threads of the threaded opening I! are right handed threads, so thatas the screw 18 is unscrewed, the collar 14 will be tightened within theheel and will not be unscrewed therewith.

The lower end of the collar l4 may be formed with four notches 20 atright angles to one an- 35 other. so that the same may be unscrewed by akey 2| shown in Fig. 3, and having four wings 22 adapted to be receivedwithin the notches 20.

The lower end of the screw I8 may be formed with a longitudinal slot 24,and may be unscrewed 30 by a key 25 having a blade 26 adapted to bereceived within the key slot 24.

Preferably only the screw contacts the ground, and as the same wears thewear may be compensated by unscrewing the screw. The slot 24 35 istherefore preferably of considerable length, so as to get more wear outof the screw. The screws I 8 may be replaced when worn away.

If desired the slot 24 may extend all the way through the screw l8, sothat more wear can be 40 obtained with said screw.

In Fig. 5 there is shown a screw 18a, similar to the screw 18, buthaving a hexagonal opening 30. In Fig. 6 there is shown a wrench 3|which may be used to unscrew the screw l8a from the 46 collar M. Theopening 30 may also extend all the way through the screw 18a, so as topermit use of the screw l8a for longer periods.

In Fig. 7 there is shown a ladys shoe 35, provided with a heel 36 havinga tread portion or 50 lift 31. The lift 31 is provided with screwthreaded openings I2 to receive the collars l4 and the inner screws 18,as shown in Figs. 1 and 2 of the drawing.

It will thus be seen that there is provided 9. cl

device in which the several objects of this invention are achieved, andwhich is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention,and as various changes might be made in the embodiments above set forth,it is to be understood that all matter herein set forth or shown in theaccompanying drawing is to be interpreted as illustrative and not in alimiting sense.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. A heel having a vertical screw threaded opening, a member screwedwithin said opening,

and having an internally screw threaded opening therein, and a screwscrewed within said internally screw threaded opening, the externalscrew threads of the tubular member being coarser than the threads ofthe internally screw threaded opening, and extending in a directionopposite to, the threads of said internally screw threaded opening.

2. A heel having a vertical screwthreaded opening, a member screwedwithin said opening, and having an internally screw threaded openingtherein, and a screw screwed within said internally screw threadedopening, the external screw threads of the tubular member bein coarserthan the threads of the internally screw threaded opening, and extendingin a direction opposite to the threads of said internally screw threadedopening, said tubular screw threaded member terminating short of thebottom surface of the heel, and the lower end of said screw being flushwith the under-surface of said heel.

3. A heel having a vertical screw threaded opening, a member screwedwithin said opening, and having an internally screw threaded openingtherein, and a screw screwed within said internally screw threadedopening, the external screw threads of the tubular member being coarserthanthe threads of the internally screw threaded opening, and extendingin a direction opposite to the threads of said internally screw threadedopening, said tubular screw threaded member terminating short of thebottom surface of the heel, the lower end of said screw being flush withthe under-surface of said heel, the lower end of said tubular memberhaving notches to receive a wrench, and the lower end of said screwhaving a wrench opening.
